UNITED STATES PATENT CFFIGE.

JOHN L. ALEXANDER AND WILLIAM E. ALEXANDER, F HAZELRIGG, IND.

BAN D-CUTTER.

SPECIFICATION forming part of Letters Patent No. 235,483, dated December 14, 1880.

Application filed September 1, 1880. (Model) To all whom it may concern:

Be it known that we, JOHN L. ALEXANDER and WILLIAM E. ALEXANDER, of Hazelrigg, in the county of Boone and State of Indiana, have invented a new and useful Improvement in Band-Cutters, of which the following is a specification.

Figure 1 is a front elevation of the im-' provement. Fig. 2 is an under-side view. Fig. 3 is a sectional end elevation of the improvement, taken through the line a; m, Fig. 1.

. apron to feed the bundles to the platform, a

self-adjusting toothed cylinder and its driving mechanism to feed the bundles across the platform and the loose grain to the table, a revolving knife and its supporting-bar and driving mechanism, and a connecting-bar and crank to swing the revolving knife back and forth and insure the cuttingof the bands, as will be hereinafter fully described.

A represents the ordinary baud-table, which is secured to the frame of the thrasher at the side of the feed-table in the usual manner. Upon the rear part of the table A is placed a bench or platform, B, upon which 'the bundle rests while the band is being out. With the rear side of the platform B is connected the lower edge of the. inclined apron or chute 0, down which the. bundle slides to be cut. The bundle is fed across the platform B by the cylinder D, which maybe made in skeleton form, if desired, and to which are attached spikes or teeth E, to take hold of the grain and feed it forward.

The journals of the cylinder D revolve 1n slots in the standard :13, attached to the end parts of the table A, so that the said cylinder D can move up and down to adjust itself to the varying size of the bundles.

Around one end of the cylinder D is passed a belt, G, which passes over guide-pulleys H, pivoted to a standard, I, attached to the table A. The belt G passes down through an aperture in the table A, and around a pulley, J, attached to the shaft K, which revolves in bearings attached to the upper part of the frame of the table A. To the shaft Kis also attached a larger pulley. L, around which passes abelt,

The belt M also passes around a small pulley, N, attached to the driving-shaft 0, so that the feed-cylinder will be driven from the driving-shaft O. s 7

To the driving-shaft O is attached a pulley, P, to receive a driving-belt, which is designed to pass around a pulley attached to the driving mechanism of the thrasher. The shaft 0 revolves in bearings in hangers Q, or other supports attached to or forming a part of the frame of the table A. The shaft 0 passes through and revolves in holes in the lower end of the bar R, which bar rocks or vibrates on said shaft to move the knife back and forth. The lower end of the bar R is slotted or forked toweceive a pulley, S, attached to the shaft 0, and around which passes a belt, T. The belt 1 also passes around a pulley, U, placed in the forked or slotted upper end of the bar R, and attached to the short shaft V, whicht v'vorks in bearings in the upper end of the said bar B, and to one end of which is attached the knife W, by which the bands are out.

To one side of the upper end of the bar R is pivoted the end of a bar, X, the other end of which is pivoted to a crank, Y, attached to the end of the shaft K. The knife W projects through a slot, Z, in the platform B, so as to cut the band as the bundle is being fed across the said platform by the cylinder D.

With this construction the knife W will be revolved to cut the band, and at the same time will be swung back and forward through the slot Z by the action of the connecting-bar X and crank Y, so as to be sure and strike the band as the bundle is passing over the platform B.

The knife W, when designed for cutting straw bands, is made circular and with a substantially as herein shown and described.

2. In a band-cutter, the combination, with i the revolving knife and band-table A, of the i platform B, having slot Z to receive the knife,

and the connecting-bar and crank, 1

the inclined feed-apron G, the self-adjusting :0 toothed cylinder 1) E, revolving in slotted standards, and its driving mechanism, substantially as herein shown and described,

| whereby the bundles will be fed to the knife and the loose grain to the band-table, as set 25 forth.

3. In a band-cutter, the combination, with the table A, the slotted platform B, and the toothed cylinder 1) E, of the revolving knife W, its supporting rocking-bar R, and its drivo iug mechanism, substantially as herein shown and described.
